Automatic update via the Internet

The easiest and safest way to get the latest version of the software is to use the built-in mechanism. OTA (Over-the-Air. for your Smart TV You need a stable Wi-Fi connection or a wired Ethernet cable, and the system will check the manufacturer's servers and suggest installing an available version.

The process of finding updates can take anywhere from a few seconds to a couple of minutes, depending on the speed of your Internet connection. If servers are congested, for example, on the day of a major update, it may take longer to check, in which case you should not panic, just try again after a while.

To start the check, go to the main menu and select Settings. Next, follow the About Device or System path where the System Update button is located. If a new version is found, a corresponding notification will appear on the screen prompting you to download and install the data packet.

It is important to note that automatic updates require free space in internal memory. If the storage is full of applications, the system may not offer an installation or the process will end in error, it is recommended to free up at least 500 MB of free space in advance.

Manual installation of firmware via USB

If the TV doesn't have access to the network, or if the automatic check doesn't find updates, you have to use the manual installation method, which is often called "offline upgrade." You need a computer with Internet access and a computer with a computer with a computer with a computer with a computer with a computer with a computer with a computer with a computer that has a computer that has a computer that has a computer that can use it. USB-USB flash drive from 4 to 32 GB formatted in the file system FAT32.

The first step is to find the right firmware file. It is essential to download the archive specifically for your model, marked on the sticker at the back of the case. Installing incompatible firmware can lead to irreversible consequences, so double-check the model number (for example, L32M5-5ARU or L43M5-5ASP).

Once you download the archin from the official website or a trusted forum, extract the update file (usually.bin or in a folder called update) to the root of the flash drive. Do not put it in folders, otherwise the TV will not be able to detect it. USB-TV port, preferably in port 2.0 black, not blue 3.0.

The TV should find the new file itself and suggest that you start updating. If that doesn't happen, go to the Media or Explorer menu, find the file on the flash drive and run it manually. During the process, the screen may go out or reboot, which is normal system behavior.

Update of PatchWall TVs

Many modern Xiaomi models, especially those released for the CIS and Europe, are based on the PatchWall shell. This is a modified version of Android TV with its own interface and update system. The principle of finding updates here is similar to classic Android, but the layout of the menu may differ.

Often, users can't find the update button because they're looking for it in the standard Android menu. In the PatchWall interface, settings are often hidden in the user profile or in a special service section. Click the menu button on the remote and select the gear icon in the upper right corner.

In some versions of PathWall firmware, automatic updates can be disabled by default to save traffic. Check network settings and make sure the date and time are set correctly. Wrong time can block the connection to the update server due to a security certificate error.

If the menu update doesn’t start, try the flash drive method described above.The PatchWall file system also supports external updates, which is a versatile solution for all shell modifications.

Using ADB for Advanced Users

For power users who want to have full control of the process, the Android Debug Bridge (ADB) update method is available, which allows you to install firmware even when the standard menu is not working, you will need a PC, a USB-USB cable (or USB-microUSB, depending on the port on TV), and installed ADB drivers.

First, activate the developer mode. Go to Settings → About device and quickly click 7 times on Build Number. After the message “You became a developer” appears in the settings menu, a new section for developers will appear.

In this section, turn on USB Debugging and connect the TV to your computer. The TV screen will see a request for debugging permission — confirm it. Now you can send commands to your device via the Windows or Terminal command line in macOS.

adb connect 192.168.1.XX


adb sideload update_package.zip

Using the adb sideload command allows you to send the update zip archive directly to Recovery, a method that is considered more reliable when restoring bricks, but requires strict adherence to the command syntax. A single-letter error can lead to the command not executing.

Solving common mistakes

The update process doesn’t always go smoothly. Users often encounter a message that says “failed to update” or a hang on the Android logo. Below is a table with the most common problems and ways to solve them.

If the TV is off the bootloop, try a Hard Reset, which usually requires pressing the power button on the TV body (not the remote) while you're on, which will delete all user data, but can restore the system to work.
